Understanding the Glycemic Index

You've probably never heard of the Glycemic Index. Well, now you have! The glycemic index is a relatively easy to understand rating system for ranking carbohydrate based foods.

A low rating on the glycemic index means that the food does not spike blood glucose and insulin levels quickly within the body.

Now you might wonder why that is important.

Foods that raise blood sugar levels quickly increase the chance of developing diabetes and heart disease but they also contribute heavily to weight gain. High GI carbohydrates are typically foods that don't keep you full for very long, like white bread and junk food, and instead you gorge yourself on half a loaf of bread or an entire bag of potato chips because you still feel hungry.

The glycemic index food chart above is a guide of which foods have a low, medium or high GI rating. By choosing healthier foods off of this list, it creates a very simple way to improve your nutrition without having to do a lot research/buying diet books/learning to count calories, etc.

The Glycemic Index is not just for weight loss. Regular exercise enthusiasts and athletes benefit from choosing low GI food. Low GI food before exercise maintains blood sugar concentration and increases the rate of stored fat being used for energy (fat oxidation). Low GI foods before exercise have been shown to increase endurance.
